We need to prevent creating new types in a specific index?

Dynamic index creation can be disabled via: `action.auto_create_index: false (via config/elasticsearch.yml)`  
Dynamic field mapping can be disable during mapping definition: `"dynamic": "strict"`

How can I disable this for a document-type? Is this possible at index creation time?

Did you try `"index.mapper.dynamic" : "false"`? According to the explanation given for [Mappers](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-mapper.html) this should work.

Thanks Christoph, that works!  
I thought it could only be used in the _elasticsearch.yml_ globally. But it works also at index-creation time in the settings.
